Although the Slipknot can be disassembled and placed directly onto the rope, it's much easier to thread the line right through it. Remember to add two, one for each end. Twist the Slipknot with two hands in opposite direction to either tighten or loosen. Once loose, you can move the Slipknot up and down the line. Keep about 4 feet from the anchor points (tree, post, or pole) to help prevent your dog from wrapping itself around it.
